Abstract: Wire arc additive manufacturing-spinning combined machining device and method are provided. The machining device includes a spinning mechanism and a fused deposition modeling mechanism. The spinning mechanism includes a machine tool and a spinning head. The spinning head is installed on the machine tool by a main shaft, and the main shaft is configured to drive the spinning head to rotate to achieve the movement in three vertical directions. The spinning head includes a spinning base and balls. Each of the balls is installed in a corresponding one of arc grooves at a bottom of the spinning base. The fused deposition modeling mechanism includes a moving track, a robot and a heat source generator. The arc moving track is arranged around the machine tool in a surrounding mode. The robot is movably installed on the moving track. The heat source generator is installed at a tail end of the robot.
